Shave a fraction of a second off Time Trial/Fast Lap Challenge race/lap times:

At the start of a Time Trial/Fast Lap challenge, you start a few meters behind the starting line. The timer only starts once you cross the starting line, so turn around at the start of a race, drive the wrong way until you reach top speed. Now, turn around and race towards the starting line. This way, you can cross the starting line at full speed and thus save some time that would have been wasted reaching top speed.
